DECT DATA and Multimedia

In 1998 DOSCH&AMAND released the development of multimedia-enabled DECT generation DPRS/DMAP (ETSI Standards EN 301 649 / EN301 650).

The achievement of EN 301 649 DECT Packet Radio Service (DPRS) and EN 301 650 DECT Multimedia Access Profile EN 301 50 has been an important step forward for the development of DECT data application, introducing the flexibility and resources optimization of packet technology, opening the field to further developments in terms of speed and profiles. The Project responded in this way to the growing demand for the support of data services and the continuous desire to increase available data rates by adding high bit rate modes to DECT. The third version of DECT Packet Radio Service (DPRS) EN 301 649 in support of data applications, was published; this supports the transmission of high-speed data (more than 4 Mbit/s of user data), for example very fast Internet access and wireless Local Area Networks.

In addition to this basic DPRS standard, a group of standards called Application Specific Access Profiles (ASAPs) has been also created. These are industry-driven standards intended to enhance interoperability. Each of them identifies a specific application scenario and selects a specific subset of DPRS services plus a voice service for particular applications.

Moreover in the field of DPRS interoperability it was published TS 101 950 the “DPRS Interoperability Test Specification. This document contains the test specification for interoperability of the DECT Packet Radio Service (DPRS). The objective is to provide a basis to test DECT equipments giving a high probability of inter-operability between different manufacturer's DECT equipment.

DMAP EN 301650 (DECT Multimedia Access Profile), developed by DOSCH&AMAND for residential/SOHO (Small Office - Home Office) applications, was the first of these ASAPs to be ready. DMAP allows for design of low-cost domestic devices for local data interconnection and Internet connection via PSTN/ISDN, which remain compatible with existing GAP handsets.

Ethernet (ETH) Interworking TS 101 942 and V.24 Interworking TS 101 947 were published. These documents define data ASAP combining a selection of Ethernet and V.24 Interworking DPRS data services. Their aim is to guarantee a sufficient level of interoperability and to provide an easy route for development of DECT DATA applications, with the features of the present document being a common fall-back option available in all compliant to this profile equipment.

DECT and F-MMS (Fixed Network MMS)

Another topic that attracted member interest is the work on Fixed network Multimedia Message Service (F-MMS)  TS 102 379 Interworking Profile to provide interoperable interworking between DECT PPs and FPs from different vendors supporting Fixed network Multimedia Messaging Service (F-MMS) based on service/network specifications standardised in ETSI AT and TISPAN
